9. the SCM Based multifunction remote-controller of one according to claim 7, it is characterized in that, described infrared encoder also includes compression coding module, for being also encoded compression after infrared coding uses formatted text mode store, compression method is: command code type: by the bootcode in infrared coding, endcode, reference key when " the having carrier wave " of sepratorcode and " not having carrier wave " time are compressed to binary coding head respectively as decoding, 16 systems are used to represent the logical zero/1code in infrared coding, complete the double byte bit digital of logical zero/1 represented by " there is carrier wave " and " not there is carrier wave " to the conversion of binary representation；
Conditional code type: bootcode, seperatorcode, the endcode in infrared coding is compressed according to protocol headers generating mode in mentioned order code type, simultaneously, step B2 obtains defaultcode, and based on defaultcode according to correction coding initial, that end logic bit position is when being subject to the change of various state.
10. the SCM Based multifunction remote-controller of one according to claim 9, it is characterised in that described IR decoder also includes coding decompression module, for being decompressed by file compressed for compression coding module.
